Radeon RX 6800 XT Overclocked to 2.80 GHz on LN2, Crushes 3DMark Fire Strike Record

One of the secret sauces of AMD's new "Big Navi" Radeon RX 6800 series GPUs is the ability for the GPU to sustain high engine clock speeds, with the company leveraging boost frequencies above 2.00 GHz in certain scenarios. It was only a matter of time before professional overclockers got their hands on an RX 6800 XT, and paired it with an LN2 evaporator. TecLab_Takukou is the new king of the 3DMark Fire Strike leaderboard thanks to their skills in running an RX 6800 XT at insane 2.80 GHz engine clocks. Takukou overclocked the RX 6800 XT to 2.80 GHz core, and 2150 MHz (17.2 Gbps) memory. This particular configuration yielded a Fire Strike score of 48890 points.

In a separate feat, with the RX 6800 XT running at 2.75 GHz, Takukou chased down the HWBot 3DMark Fire Strike leaderboard, with 49456 points. For both the 2.80 GHz and 2.75 GHz feats, the rest of the system included an LN2-cooled AMD Ryzen 9 5950X processor running at 5.60 GHz all-core, 32 GB of DDR4-3800 memory, and an MSI MEG X570 GODLIKE motherboard. From the looks of it, Takukou is using a reference-design RX 6800 XT board, so we can only hope what else can be accomplished from custom-design RX 6800 XT boards, such as the Sapphire NITRO+, PowerColor Red Devil, or ASUS ROG Strix O16G. Takukou leads the 3DMark Fire Strike leaderboard, followed by another RX 6800 XT-powered close-second, Lucky_n00b (47932 points, 2.65 GHz engine clock on air). Safedisc is third (47725 points, RTX 3090 @ 2.38 GHz).

That's almost 3Ghz on a Video Card..... wtf.......

"this isn't even my final form!"

...when thinking that this is "only" 6800 XT, the 6900 XT can be even more interesting one.

And I was like mind = blown when I broke the magical 1GHz barrier on HD 4890 11 years ago.

Very nice, would like to see the 6900 XT reach the 3Ghz barrier, also I thought these cards have 128 ROPS?

Yeah, 96 on RX 6800 and 128 on RX 6800 XT and 6900 XT.

watzupkenThe clockspeed is impressive, but the power consumption will be exponentially more impressive. :oops:
No one cares about power consumption when doing LN2 overclocking and record breaking

Yep; and clockspeeds will be more important for the next generations of GPU's.

You can push lots of IPC; but that IPC is even better to use when the clocks are as high as possible.

Consider it as a highway; one highway has 8 lanes with a maximum speed of 80kmph. The other highway has 4 lanes but a maximum speed of 160. Now which one is actually faster in certain workloads?

2.8Ghz is pretty impressive. We're one to two generations away from reaching the 3GHz boost range.

The assumption that custom cards will do better is false. A lot of the times with AMD GPUs the reference board has the best VRM design, although it has to be seen how its going to be this time.

not with RX 6000, i suspect. custom AIB should be able to reach higher.
well, at least until the power limit on the reference cards can be modded, that is.

It's because AIB's tend to "skimp" out on certain quality parts which makes the production of the card cheaper and having more profit for the AIB.

Neither because of roadworks and dumbarse slow drivers hogging all the lanes.

i'm sure we'll have some good quality AIB cards with higher power limit than reference. something like power color's devil? or maybe we will see another asus' ares this time around? :roll:

Higher power limit doesn't mean better quality. The fact that the AIB cards are cheaper comes with two reasons. They get a discount from the manufacturer according to their contract and buy in bulk. Also AIBs use as minimum as possible quality components just to make the cards work a they do cheap out on the components. It doesn't mean it won't work but it means the components they use in their designs are cheaper. That of course depends on the tier of the card Sapphire pulse will be cheaper than nitro+ that's for sure.

The way you said it seams like good quality comes with higher power limit since you compare it to a reference cards.
Either way, AIBs cards are cheaper for a reason and it doesn't mean they use quality components. They do but mostly they use bare minimum to make it work.

what i meant: good quality AIB cards with more than +15% power limit.
if you are not familiar with the +15% limit here, that's what the reference tops at right now.
to be clear: I never said higher power limit equals to good quality.

now, not all AIB cards are cheaper than reference. e.g. asus ROG strix, sapphire nitro+, power color devil - at least in my country.
of course not the el cheapo one like tuf or pulse :roll:

Pfffff my card does over 6000 mhz.

On the memory.

Ampere: It's Over NAVI! I have the TFLOPS high ground
BiG NAVI: Don't underestimate my powers
Ampere: Don't try it

Result: BiG NAVI's frame rate was sliced in half with ray tracing.
